Serial Killer

A Serial Killer is a player whose goal is to be the last player alive. They are aligned with themselves (meaning they have no allies) and have a factional kill at Night like the Mafia. Depending on the flavor, SKs may also be called Cannibals, Psychopaths, or Arsonists (note that Arsonist has since grown to describe a unique role).

Most moderators will not allow Towns or Mafias to win while a Serial Killer is still alive.

Serial Killer and its variants below are or can be considered Normal on mafiascum.net. Incidentally, Psychiatrist is not.

Variations

Serial Killer is the most difficult standard faction to win as, since being the sole survivor requires the player to dodge all of the Town's lynches and the Mafia's Night-kills. Thus, they are generally given a boost of some kind, depending on the game.

Serial Killers are often awarded the win if all players die, typically done by wording the win condition akin to "you win when all other players are dead, whether you are alive or not".

Serial Killers are often given One-Shot or unlimited Bulletproof. This stymies attempts to kill the SK by the Mafia or Vigs, if temporarily.

In very complex games, Serial Killers can be complex roles unto themselves that just happen to have a factional kill and a self-aligned win condition.

Use and Power

Serial Killer exists to ratchet up the death count per Night and raise the swing of the game tremendously due to the SK's independent motivation. These are somewhat desirable in fairly stable Large games, but in role madness or smaller games SKs tend to lead to uncomfortable situations where their actions play a disproportionate role in deciding the game. This can be mitigated somewhat by including a Vigilante instead.

Play Advice

If you draw Serial Killer, do not claim NK-ImmuneMillerVig. Although since that meme has appeared, some moderators actually have included that very role in their setups... Nonetheless, you are usually best off not claiming to be a Vigilante if you are a Serial Killer unless you are incriminated by a Tracker or Watcher result.
